 ## Introduction
 
 DiffSynth Studio is a Diffusion engine. We have restructured architectures including Text Encoder, UNet, VAE, among others, maintaining compatibility with models from the open-source community while enhancing computational performance. We provide many interesting features. Enjoy the magic of Diffusion models!
 
-## Roadmap
+Until now, DiffSynth Studio has supported the following models:
 
-* Aug 29, 2023. We propose DiffSynth, a video synthesis framework.
+* [CogVideo](https://huggingface.co/THUDM/CogVideoX-5b)
-    * [Project Page](https://ecnu-cilab.github.io/DiffSynth.github.io/).
+* [FLUX](https://huggingface.co/black-forest-labs/FLUX.1-dev)
-    * The source codes are released in [EasyNLP](https://github.com/alibaba/EasyNLP/tree/master/diffusion/DiffSynth).
-    * The technical report (ECML PKDD 2024) is released on [arXiv](https://arxiv.org/abs/2308.03463).
-* Oct 1, 2023. We release an early version of this project, namely FastSDXL. A try for building a diffusion engine.
-    * The source codes are released on [GitHub](https://github.com/Artiprocher/FastSDXL).
-    * FastSDXL includes a trainable OLSS scheduler for efficiency improvement.
-        * The original repo of OLSS is [here](https://github.com/alibaba/EasyNLP/tree/master/diffusion/olss_scheduler).
-        * The technical report (CIKM 2023) is released on [arXiv](https://arxiv.org/abs/2305.14677).
-        * A demo video is shown on [Bilibili](https://www.bilibili.com/video/BV1w8411y7uj).
-        * Since OLSS requires additional training, we don't implement it in this project.
-* Nov 15, 2023. We propose FastBlend, a powerful video deflickering algorithm.
-    * The sd-webui extension is released on [GitHub](https://github.com/Artiprocher/sd-webui-fastblend).
-    * Demo videos are shown on Bilibili, including three tasks.
-        * [Video deflickering](https://www.bilibili.com/video/BV1d94y1W7PE)

-    * The technical report is released on [arXiv](https://arxiv.org/abs/2311.09265).
-    * An unofficial ComfyUI extension developed by other users is released on [GitHub](https://github.com/AInseven/ComfyUI-fastblend).
-* Dec 8, 2023. We decide to develop a new Project, aiming to release the potential of diffusion models, especially in video synthesis. The development of this project is started.
-* Jan 29, 2024. We propose Diffutoon, a fantastic solution for toon shading.
-    * [Project Page](https://ecnu-cilab.github.io/DiffutoonProjectPage/).
-    * The source codes are released in this project.
-    * The technical report (IJCAI 2024) is released on [arXiv](https://arxiv.org/abs/2401.16224).
-* June 13, 2024. DiffSynth Studio is transfered to ModelScope. The developers have transitioned from "I" to "we". Of course, I will still participate in development and maintenance.
-* June 21, 2024. We propose ExVideo, a post-tuning technique aimed at enhancing the capability of video generation models. We have extended Stable Video Diffusion to achieve the generation of long videos up to 128 frames.

+### Video Synthesis
+
+#### Text-to-video using CogVideoX-5B
+
+CogVideoX-5B is released by ZhiPu. We provide an improved pipeline, supporting text-to-video, video editing, self-upscaling and video interpolation. [`examples/video_synthesis`](./examples/video_synthesis/)
+
+The video on the left is generated using the original text-to-video pipeline, while the video on the right is the result after editing and frame interpolation.
